Abstract
The present invention relates to a kind of Halogen melt-drip resistant inflaming retarding nylon 6 resin and preparation method thereof, structural formula is:
Description
Technical field
The invention belongs to flame-retarded resin and its preparation field, more particularly to a kind of Halogen melt-drip resistant inflaming retarding nylon 6 resin and
Its preparation method.
Background technology
Nylon 6 is that a kind of burning velocity is fast, and the high high polymer material of heat release amount can also discharge in combustion in addition
A large amount of dense smokes and with the phenomenon of molten drop, can be caused serious injury to human body and ecological environment.Current numerous researchers
In order to improve the combustibility of nylon 6, many research work have been done, it is also just gradually good to environmental protection, combination property
Direction is developed.
Patent CN 104311877A are related to a kind of response type nylon fire retardant and preparation method, it is characterised in that:Halogen contains
Phosphorus copoly type fire retardant elder generation and diol reaction, obtain fire-retardant esterifying liquid;Then halogen-free phosphorus-containing nylon is obtained with binary acid reaction
